CAR DOOR.

To all whom. it may concern Be it known that I, Josnrrr J. Lace, acitizen of the United States, residing at Lumberton, in the county ofLamar and State of Mississippi, have invented certain new and usefulImprovements in Car Doors, of which the following is a specification.

This invention relates to car doors, and it vcomprises a track arrangedabove the door opening, an upper door section having brackets securedthereto, rollers carried by said brackets and engaging said track, alower section provided with a longitudinal groove on its lower edge, aplate secured to the floor and entering said groove, and locking meansfor said door, said means comprising an angle iron carried by each ofsaid sections adjacent one side of the door, an angle iron pivotallymounted in the doorwayand adapted to engage said angle irons to preventmovement of the door, and an arm carried by said pivoted angle iron andadapted to be fastened to the door.

In the present invention, I have provided an improved type of slidingdoor for cars wherein the door is made in two sections, the uppersection being adapted to slide over the lower section and be mounted ona track arranged above the doorway. An interlocking tongue and grooveconstruction is provided at the meeting edges of the two sec tions toprevent the upper section from becoming displaced. The door sill isprovided with an upwardly extending plate adapted to enter alongitudinal groove in the lower section to retain the lower section ofthe door in place. Means are provided for rear il and quickly lockingand sealing the ooor, comprising a pin or rod projecting from one ofsaid sections and adapted to pass through an opening in a pivoted armcarried by the other section. The two sections of the door are thusmaintained locked to each other, and when the upper section is to beopened, the hinged arm is disengaged from said pin to permit movementthereof. The two sections are retained in closed position by means offlanged plates projecting from the outside of the door and adapted tobeengaged by a hinge or pivoted plate mounted on the door casing. Thisplate is provided with an arm extending over said rod or pin, and

having an opening for the reception of said rod or pin. hen the door isin closed po-v sition, and the two arms are arranged over said rod, alock or seal 18 arranged in an Specification of Letters Patent. PatentedlIar 1922 Application filed April 2,

1921. Serial No. 457,867.

opening in the end 01" the rod to prevent unlawful manipulation of thedoors of the car.

In the accompanying drawings, I have shown one einbodiment'of theinvention. In this showing:

Figure 2 is a transverse vertical sectional view on line 2-2 of Figure1,

Figure 3 is a similar view of a portion of the door on a slightlyenlarged scale,

F igure lis a similar viewv of the upper section of the door on aslightly enlarged scale, I

Figure 5 is a horizontal sectional view on line of Figure 1,

Figure 7 is a detail perspective view of the upper door section,

Figure 8 is a similar view of the lower section,

Figure 9 is a detail view of the'locking member, and,

Figure 10 is a similar view of a lock or seal.

Referring to the drawings, the reference numeral 1 designates anordinary type of freight car which is provided with a roof 2,.

and a floor 3. The side of the car is provided with an opening ordoorway 4, and a track 5 is arranged over the doorway and extended intoa housing 6, for-the reception of the door when in open position. The

floor of the-car is provided withthe usual,

sill 7, having an upwardly extending flange or guide 8, whlch is alsoextended into the housing 6 (see Figure 5).

The door comprises a lower section 9, and

an upper section 10. As shown, the lower section is provided with alongitudinal groove 11 on its lower edge, for the reception of theupwardly extending plate or rib '8. The upper edge of the lower sectionof the door is cut away at each side to provide a projecting tongue 12.A pair of plates 13 are secured to the lower edge of the upper sectionforming a groove for the'reception of tongue 12, to retain the twosections of the door in proper vertical alinement. A plurality ofbrackets 14 are secured to the upper edge or: the upper door section,the brackets extending upwardly beyond the upper edge of the upper doorsection and being provided with a substantially inverted U- shapedportion 15. Rollers 15 are journaled in the arms of the invertedU-shaped portion of the bracket, and these rollers are adapted to rideon the track 5 and support the door. As shown, the rollers are providedwith grooves 17 to prevent them from becoming displaced from the track.

The upper section of the door is locked to the lower section by means ofa hinged arm 18, secured thereto at any suitable point and adapted tonormally lie in a recess 19 in the face of the upper door section sothat the arm, when in closed position, will lie flush with the surfaceof the door (see Figure 2). The lower door section is provided with agroove or recess 20, through which the lower end of arm 18 extends whenthe two sections ot the door are in closed position. A locking pi n 21is arranged on the lower door section and this pin is adapted to passthrough an opening 22 on the end of the arm 18 when the doors are inalinement with each other. As shown, the lower end of the arm is offset,as at 23, to permit the locking elements to be arranged substantiallyflush with the surface of the door. The lower door section is pro videdwith a horizontal groove or recess 24, for the reception of the offsetend of the hinged arm which )ermits the arm to be arranged substantiallyflush with the face of the door when in unlockednosition with thesections of the door out of alinement with each other.

Each of the door sections is provided with an outwardly extending flange25, adjacent its outer end. When the door is in closed position, theseflanges are adapted to be arranged beside the side wall 26 of the doorframe. A locking member 27 is pivotally mounted in the doorway, thelocking memher being provided with ears 28 for the reception of pivotpins. As shown, the locking member is formed of angle iron, and comprises a pairof arms 29 and 30, the arm 29 being arranged transverselyof the car and abutting the flanges 25 when in closed position (seeFigurefi), and the arm 30 being arranged along the outer face Of thedoor. The arm 30 is provided with an extension 31, having an offset end32, which is adapted to enter the groove2 l. The offset end is providedwith an opening 33, for the reception of the lockingpin 21.

\Vhen the door is in the position shown in Figures 1 to 3 of thedrawings, the hinged arm 18 is arranged over the locking pin to retainthe two door sections in vertical alinement, and the offset end 32 ofthe extension 31 is then arranged over the locking pin. Any suitabletype of locking means may be arranged in an opening 34:, arranged in thelocking pin to retain the arms 31 and 18 on and lz-eing adapt-ed to thepin. A seal 35 may be attached to a chain 36, carried by the extension81, and passed through the opening 3%, as shown in l igures 2 and 3.Atter the seal has been placed inposition, it may be closed and the carsealed.

When the car is to be opened, the seal or other locking means is firstremoved, and the locking member 27 turned at right angles to theposition shown. It will be apparent that the flange 25 will then be freeto move, per-= mitting the door to be opened. It merely the uppersection of the door is to be opened, the arm 18 is removed from the endof the locking pin to permit independent movement 1. A car doorcomprising upper and lower sections slidahly mounted in the side of acar, anarm hinged to one of said sections and extending over the othersection, said arm being provided with an opening adjacent its tree end,a locking pin carried by said second section and adapted to be receivedin said opening, said door sections being provided with outwardlyextending flanges adjacent one end, an angle iron hinged tothe car, onearm oi said angle iron being adapted to engage said flanges, when inclosed position, the other arm thereof be ing arranged substantiz'illyparallel to the race at the door, and an extension arranged on saidsecond arm, said extension being pro vided with an opening adjacent itstree end receive said locking pin.

2. A car door of the clnn'acter set forth in claim 1.. wherein said doorsections are provided with substantially vertical grooves adapted toaline wit-h each other when the door is closed, said first mentioned armbeing adapted to be arranged in said grooves, and wherein the lower doorsection is provided with a horizontal. groove adapted to receive theextension formed on said second arm.

In testimony whereof I affix my signature in presence of two witnesses.
